It introduces that the semi-rigid basis has the merits of low cost and high strengthen,researches the function of rubber asphalt, the effect of water proof,the diameter of detritus,and points out that it can proof the water and the reflecting crack of making the semi-rigid basis as rubber asphalt detritus under-sealed layer(SAMI),it is a kind of more economical function layer.
介绍了半刚性基层具有的造价低、强度高等优点,对橡胶沥青的性能、防水效果、碎石粒径等方面进行了研究,指出在半刚性基层上做橡胶沥青碎石下封层(SAMI),可以起到防水、防反射裂缝等作用,是一种相对经济的功能层。
